摘要: 针对某微小卫星, 研究了系统结构存在不确定性及外部干扰为定常未知时的姿态控制问题. 运用Lyapunov 方法, 利用Euler-Lagrange 系统的内在性质, 设计出一种不需解耦的鲁棒自适应控制器. 对系统进行数学仿真表明, 该控制算法在应用中不但具有较好的控制性能, 还具备良好的鲁棒性.Abstract: The attitude control problem of certain microsatellites with uncertainty structure and unknown but constant external interference is studied in this paper. Based on Lyapunov method and utilizing the input-output property of Euler-Lagrange systems, a robust adaptive controller without dynamics decoupling is presented. Computer simulation shows that this control algorithm possesses good control performance and robustness.
